Alteration of cardiovascular autonomic responses in obesity with different BMI level
Main Article Content
Abstract
The present study investigated the alteration of cardiovascular autonomic responses between males and females of different BMI level. Sixty healthy subjects, aged 18-25 years, participated in this study. All subjects were divided into three groups, both males and females, including normal group (BMI 18.5-24.9 kg/m2), overweight group (BMI 25–29.9 kg/m2) and obese group (BMI >30 kg/m2). Measurements were divided into four responses of autonomic function, including postural blood pressure response (PBPR) test, heart rate response to standing (HRRS) test, heart rate response to deep breathing (HRRDB) test, and blood pressure response to sustained handgrip (BPRSH) test. The result showed normal response to all autonomic function tests in both males and females at different BMI level. In conclusion, the obesity in healthy subjects may not have effect on alteration of cardiovascular autonomic responses. Bull Chiang Mai Assoc Med Sci 2008; 41: 214-224.
